Racket is very academic, but Common Lisp (SBCL is an implementation of the CL standard) is not really academic in my opinion its mostly an industrial language. It is an incredibly practical language and its exactly what I reach to to crank a weekend webapp. Its fast and unopinionated and the repl is a godsend for the quick iteration required to do a weekend hack. I think it may just look like that from the outside due to preconceived notions of what lisps are. CL mostly allows you to do whatever you want, at its core it is a compiled, imperative, garbage collected language, with incredible interaction and introspection capabilities and the ability to modify the language in a very straightforward way (take code, modify code). It just has a weird syntax to be able to do macros and reason about macros
